`BufferedSink` and a `ResponseBody` as an Okio `BufferedSource`. Standard
    `InputStream` and `OutputStream` access is also available.

 *  **New Call and Callback types** execute requests and receive their
    responses. Both types of calls can be canceled via the `Call` or the
    `OkHttpClient`.

 *  **URLConnection support has moved to the okhttp-urlconnection module.**

Это особенно заметно при использовании `docker compose`.

#### Структура директорий { #directory-structure }

Теперь у вас должна быть такая структура:

Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

	ch := make(chan itemOrErr[string])

	go func() {
		defer xioutil.SafeClose(ch)

		// Allocate new results channel to receive ObjectInfo.
		objInfoCh := make(chan itemOrErr[ObjectInfo])

		if err := objAPI.Walk(ctx, minioMetaBucket, pathPrefix, objInfoCh, WalkOptions{}); err != nil {
			select {
			case ch <- itemOrErr[string]{Err: err}:

	}
	for group := range info.GroupStats {
		c.healGroupPolicies(ctx, objAPI, group, info)
	}

	return nil
}

// heal iam policies present on this site to peers, provided current cluster has the most recent update.
func (c *SiteReplicationSys) healPolicies(ctx context.Context, objAPI ObjectLayer, policy string, info srStatusInfo) error {
	// create IAM policy on peer cluster if missing
	ps := info.PolicyStats[policy]

  You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,
